The Goodman A3468601 is a genuine OEM 3/16" inner-diameter pressure switch tubing designed for the Goodman/Amana AMH80604BNBA gas furnace. This flexible silicone hose connects the inducer draft port to the pressure (vacuum) switch, allowing the switch to verify proper venting and combustion airflow before the ignition sequence begins. Cracked, hardened, or disconnected tubing is one of the most common causes of intermittent no-heat and pressure switch lockout faults.

Specifications

Inner diameter: 3/16 in.
Material: High-temperature silicone/PVC hose
Application: Draft/vacuum pressure switch line
Fit: Goodman & Amana 80% AFUE gas furnaces incl. AMH80604BNBA
OEM Part #: A3468601

OEM vs. Generic

The OEM A3468601 hose is manufactured to exact bore and wall specs so the pressure switch reads the correct negative pressure — critical for reliable ignition. Universal aftermarket tubing may vary in ID and flexibility, causing false pressure switch trips or slow air leaks. Choose OEM for guaranteed sensing accuracy and long service life.

Installation Difficulty

Easy (1/5). Slide the new hose onto the port and switch barb; no tools required. Always shut off power and gas before servicing. Typical replacement time is under 5 minutes.

Frequently Asked Questions

Does this Pressure Switch Tubing fit my Goodman AMH80604BNBA — A3468601?

Yes. This is the factory-specified OEM pressure switch tubing for the Goodman AMH80604BNBA — A3468601. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the pressure switch tubing on my Goodman AMH80604BNBA — A3468601?

Difficulty: Medium (20–30 min)
Step 1: Turn off power. Step 2: Locate pressure switch near draft inducer. Step 3: Note tubing orientation. Step 4: Disconnect tubing and wires. Step 5: Remove screw, install new switch. Step 6: Reconnect tubing and wires, restore power.

My furnace shows a pressure switch error. What do I replace?

Furnace LED showing pressure switch error = switch not detecting draft inducer airflow. Try first: clear the rubber tubing to the switch (often clogged with condensation). If problem persists, replace the pressure switch.

Is this pressure switch tubing compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Goodman pressure switch tubing?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
